The external model design model of creating the system function is mainly to consider the data structure, the overall structure and the process description of the software,
The interface design is usually only used as accessories, only on the user''s situation (including age, gender, mental status, education level, personality, ethnic background and etc A960GOT-EBD Operating Manual A960GOT-EBD ) to understand, to design an effective user interface;
According to the user model of the future system of the end user (for short),
In the end, it is consistent with the system image (external characteristic) of the system after the system is realized,
Users can be satisfied with the system and be able to use it effectively;
When the user model is established, the information given by the system should be considered,
System mapping must accurately reflect the syntax and semantic information of the system A960GOT-EBD Operating Manual A960GOT-EBD Operating Manual.
In short, only to understand the user, to understand the task in order to design a good man-machine interface. Input points: 32 points.
Voltage: DC12/24V.
Current: 4/10mA.
Response time: 10ms.
8 points / a common end.
Cathode common.
38 point terminal station.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the compponent image register are changed with the change of the execution of the program A960GOT-EBD Manual.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A960GOT-EBD Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
